European H. SJmttleworth'i. I find iu my collection no species analo- 

 gous to H. borealis and hffea. Possibly a new genus allied to Dasys- 

 toma belongs here ; it should contain Wujacophila onicrocepliala and R. 

 setifera, Pictet, Dasystoma nigrum, Brauer, and two or three new species 

 from Spain, Switzerland, and Bavaria. The neuration is similar, 

 especially iu the posterior wings, but the spurs are very short and less 

 in number. 



As I have said in the Stett. Zeit., 1864, p. 132, the genus Molan- 

 nodes, McLachlan (to which belongs Pot. Pictetii, Kolenati) has perhaps 

 a right to these cases. The neuration differs somewhat from Helico- 

 psyche ; but otherwise the habit, legs, spurs, antennae, hairy palpi, &c., 

 are similar. I should add that the maxillary palpi of Mr. Bland's 

 examples were broken en route, and that I have described them after 

 the types of Notidohia horealis ; but it is always very difficult to dis- 

 tinguish the number of joints in these hairy palpi.

[Note. — The character of my genus Molannodes will shortly 

 appear in the Ann. Soc. Ent. Erance. That genus has undoubtedly 

 five joints in the maxillary palpi of the male, and belongs to the Lep- 

 toceridce, coming near Molanna. Mr. Scudder, of Boston, informed 

 me that in America the cases of Helicopsyclie are generally found 

 attached to the outside of large bivalve shells of the genus TJnio. The 

 British Museum possesses cases from Portugal (Oporto), Jamaica, 

 Trinidad, Ceylon (Colombo), and New Zealand; those from the latter 

 locality in very large numbers and of two or three forms. The 

 solving of this hitherto difficult entomological enigma has commenced ; 

 the full solution cannot be far distant ! — R. McLachlak.] 



Omalium pineti. Thorns. — Towards the close of last year I introduced this 

 species into oar fauna, and Mr. Eye, in his paper in " The Annual," enumerated it 

 among the new species of the year, adopting, however, for it the name of lappo- 

 nicum, Zett., an alteration previously made by De Marseul in his catalogue, but 

 which cannot be maintained (as Thomson appears to have known, from the syno- 

 nyms he quotes). 



In 1830 Mannerheim described an OmaUum Icupponicum, while Zetterstedt's 

 description only bears date 1838 : I was therefore correct in the appellation I gave 

 to the insect, for Thomson's name being the next oldest to Zetterstedt's, and 

 otherwise unobjectionable, must be retained. — D. Sharp, 12, St. Vincent Street, 

 Edinburgh, Zrd March, 1866.
